Mammalian prion protein folding
WebThe GGGTHSQW sequence in the amyloidogenic part of the prion protein is a potential binding site for Cu(II). We have previously studied the binding of copper to the shorter GGGTH peptide and showed that it is highly pH dependent (Hureau et al. in J. Biol. Inorg. Chem. 11:735-744, 2006). WebAll mammals, including humans, make the prion protein PrP, but the rare, misfolded state (PrPSc) is found only in mammals with transmissible prion diseases. Remarkably, this …
